MACHINE FOR CUTTING INDEXES;

SPECIFICATION forming part of Letters Patent No. 399,250, dated March12, 1889.

Application filed March 9, 1886. Serial No. 194,658, (No model.)

To all whom it may concern-.-

Be it known that I, EDWARD P. DoxnELL, residing at Chicago, in thecounty of Cook and State of Illinois, and a citizen of the UnitedStates, have invented a new and useful Improvement in Machines forCutting Indexes, of which the following is a full description, referencebeing had to the accompanying drawings, in which Figure l is a frontelevation with the standard or support broken; Fig. 2, a side eleva- Ytion with the standard or support and the connecting-rod broken; Fig. 3,a top or plan view with the standard carrying the cutting tool insection, the tool notbeing shown; Fig. l, a perspective view showing themanner of cut-ting the index or other article; Fig. 5, a detail of thecutting-tool for making the steps; 6, a detail showing the position ofthe guides for trimming the corners; Fig. 7, a detail of the tool fortrimming the corners; Fig. 8, a detail of a punch.

This invention has for its object to construct a machine by which thecutting out oi portions of sheets of paper to form index steps orremoving pieces of a book or other article for indexing purposes can bereadily and quickh accomplished, and have the steps which are formed ofa uniform character in regard to size and the line of cut, the machinebeing also aljlapted to receive other tools for irimming the corners orpunching holes through a number of leaves or sheets of paper; and itsnature consists in the several parts and combinations of partshereinafter described, and pointed out in the claim as new.

In the drawings, A represents a stamlard or u night, having at its lowerend a base portion, A, which can be secured to a floor or other support,and having, as shown, its upper end,A, enlarged to furnish a support forthe table or bed on which the article to he operated upon is placed.

B is the bed or support attached to the top A in any suitable manner,and of the dimensions required for the size of machine.

is a sliding plate having on its under side a dovetail, l), to fit adovetailed recess, a, in the table or support B, by which means theplate is connected with the table, so that it is free to slide back andforth.

D is a stem having on its outer end a handwheel, D, and having its innerend suitably journaled in a box or hearing, D", attached to the underside of the table B at the front edge. The front edge of the slidingplate I- is provided with a rib or projecting flange, 0, the upper edgeof which is provided with a scale, and the under edge has thereon arack, with which meshes a wheel, (I, on the stem D, so that by turningthe stem through the handwhocl D the wheel (I and rack on the rib coperate to move the plate C back and forth, and the required amount ofmovement is regulated by a pointer, 11, which coacts with the scale onthe upper side of c.

E is a bar, the ends of which receive studs or pins e, extending up fromthe slide C, and receiving nuts 15', by means of which the bar E can beforced down to firmly clamp the article placed between it and the top ofthe slide.

F is a series of sheets of paper, which are to be provided with stcpsfto form an index.

G represents guides, each having a vertical. portion, and a horizontalportion, in which is a slot, q, or the mssage of a sot-screw or bolt, g,by means of which the slides can be adjusted to regulate the amount ofinward cut for the index or other art iclc, and be loclzcd firmly inposition by the sot-screws y when the proper adjustment has been made.

II is the tool, for cutting the steps for an index, which tool, asshown, has a wide cutting-edge, 72 and a narrower cutting-edge, 7t.

.I is a bar. the lower aid oi which receives the steniot'thecutting-tool ll, which is locked firmly in place by a schscrcn, i, orother suitable device.

J is a removable cap, forming one half of the box for the sliding bar I,and connected with the other half, .II', of such box by earsj on the cap.I, which coincide with projections j on the portion J, through whichearsj and into the projcctionsj belts or screws j are passed, by whichmeans the cap J is readily removed in case it is desired to remove thesliding bar I, and by making the support for the bar in two parts abetter and more accurate fit between the reciprocating bar I and itssupport can be made.

K is an arm, with which is formed the portion J of the support for thebar Land, as shown,this.arn1 at its lower end has a base or flange, K,through'which bolts or screws 7c pass for attaching the arm to the bedB.

L is an upright or post extending up from the arm K and formed therewithin the construction shown.

M is a cross-bar, one end of which is pivoted by a suitable pin orpivot, Z, to the upper end of the standard L, and the other end ispivoted by a suitable p in or pivot, m, to the upper end of the bar I.

N is a connecting-roc'l, the upper end of which is screw-threaded toreceive a nut, 02, and this upper end is connected with a fork, N, whichis attached to the bar M by a suitable pin or pivot, 71', and the lowerend of the rod is connected with a fork,N. This rod N passes through thearm K, and a nut, n, is arranged to strike against the top of the arm K,and thereby limit the downward thrust of the bar I, and consequently thestroke of the cutting-tool H.

O is a foot treadle or lever, the attached end of which is connected toa standard, 0, bya suitable pin or pivot, 0, the standard 0 beingattached to the base-plate A by bolts or screws 0, and to this foottreadle or lever 0, back of the standard 0, is attached the fork N by asuitable pin or pivot, n".

P is a coiled spring, one end of which is connected wit-h the foottreadle or lever O and the other with a hook, p, projecting out from thestandard A.

Q is a foot-rest attached to the free end of the treadle or lever O.

The operation is as follows: The leaves or sheets for the index F areplaced beneath the clamping-bar E, and by means of such bar and theset-nuts c clamped firmly to the slide 0, before which the gages orguides G are adjusted for the required depth of incut,

and in putting the leaves beneath the clamp they are reversed inposition from that which they will occupy when the index is completethat is, the bottom of the index will be the top leaf or leaves. Theslide 0 is carried back for the required width of cut for the firststep, and the leaf or leaves which form the bottom of the index areturned back, as shown in Fig. 4, when the operator, placing his foot onthe lever or treadle O, forces down such lewer or treadle, carrying downthe rod N and the outer end of the bar M, forcing the slide-bar I downand giving the stroke to the cutting tool H, to force such tool throughthe remaining leaves of the index, so that when the leaves which havebeen turned back are dropped down a step will be formed. The tool isthen withdrawn by the operator removing his foot from the treadle orlever O, which leaves the spring Pfree to throw the lever up and throughthe rod N and bar M carry up the bar I and the cutting-tool l-I. Thenthe number of leaves for the next step are turned back and thecutting-tool again forced down through the lever or treadle O, formingthe next step on those leaves which have been turned back, and thisoperation is repeated until the full number of steps have been formed.The steps are regulated in size by the scale on c, in connection withthe pointer (1', through which the advance of the slide 0 from the wheeld and rack-bar 011 c is regulated to a uniformity. The leaves at thecompletion of the cutting are removed from the table by loosening theclamping-bar E, when they can be turned over, and a stepped index willbe had on which can be placed lettcrsor other references, as may bedesired.

The machine will be found useful in cutting indexes for letter-files,index-books, or other books where steps are required, and forcutting-leaves and books for the purpose of forming a step or inset toreceive reference-marks.-

The machine when used for indexes can also be made to cut the holes inthe indeX- leaves for the fastening cord or wire by removing the tool Hand substituting therefor the punch I-l, (shown in Fig. 8,) and in caseit is desired to round the corners of the leaves which have been cut itcan be readily and quickly done by turning the guides G, as shown inFig. 6, to receive the corner of the index or book as a whole, and thenusing a tool, I as shown in Fig. 7 by means of which the corner of theindex or book can be trimmed rounding, as shown in Fig. 6.

What I claim as new, and desire to secure by Letters Patent, is+

In an index-cutting machine, the bed B, having recess a, sliding plate0, having dovetail b on its under side to enter the recess a, and sideflange, 0, provided with a" scale, and a rack on its upper and underfaces, respectively, in combination with the rod D, gearwheel (I, andpointer d, substantially as and for the purpose specified.
